| Abstract/Contents: | "UVc light has been shown to have anti-bacterial, anti-viral, and anti-fungal effects. Fungal diseases commonly impact turfgrass quality and function. An experiment was conducted in 2020 at the University of Georgia Griffin Campus in cooperation with Super-Sod to determine the potential of UVc light to reduce dollar spot disease incidence on an established seashore paspalum putting green. An Echo Robotics TM-100 turf mower retro-was fitted to automatically deliver UVc light on a nightly basis. The experimental design was a randomized complete block with two treatments, non-treated control and UVc treated, with three replications. The experiment began on May 4, 2020 and UVc treatments were continued nightly until September 9, 2020. Impacts of the treatment were monitored until early November. Visual ratings of dollar spot infection and turf quality quantified by NDVI and digital green cover were measured weekly throughout the duration of the experiment. When averaged over the entire duration of the experiment, UVc treatments reduced the number of dollar spot infection centers by 67 % and the overall dollar spot incidence by 63 % when compared to non-treated controls. Turf quality initially showed a minimal decline in UVc treated plots, but after about 30 days, turf quality of UVc treated plots measured by both NDVI and green cover % showed significant improvement over non-treated plots. This trend continued throughout the duration of the experiment. The UVc enhanced turf quality and disease suppression persisted for more than seven weeks after UVc treatments had ended. In addition, UVc treated plots also showed "growth-regulatory" type responses and were documented to have 79.5 % fewer seed heads during times of flowering, greater shoot density, and lower clip weights. Laboratory, greenhouse, and growth chamber experiments confirmed suppression of dollar spot disease and plant growth responses of seashore paspalum by UVc treatments." |
